Which message does an IPv4 host use 5 points to reply when it receives a DHCPOFFER message from a DHCP server? DHCPACK DHCPREQUEST DHCPDISCOVER DHCPOFFER 5 points What OSI layer is responsible for establishing a temporary communication session between two applications and ensuring that transmitted data can be reassembled in proper sequence? Session Transport Network Data link 5 points PCs and PC3 are on different networks separated by a router, RT. PC issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next? * RT1 will forward the ARP request to PC3. RT1 will drop the ARP request. RT1 will send an ARP reply with its own MAC address. RT1 will send an ARP reply with the PC3 MAC address. What addresses are mapped by ARP? 5 points Destination IPv4 address to the source MAC address Destination IPv4 address to the destination hostname Destination MAC address to the source IPv4 address Destination MAC address to a destination IPv4 address .docs.google.com 10 points Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.) Session Transport Network Data link Physical 5 points Which statement is true about the TCP/IP and OSI models? * The TCP/IP transport layer and OSI Layer 4 provide similar services and functions. The TCP/IP network access layer has similar functions to the OSI network layer. The OSI Layer 7 and the TCP/IP application layer provide identical functions. The first three OSI layers describe general services that are also provided by the TCP/IP Internet layer. 5 points Which message delivery option is used when all devices need to receive the same message simultaneously? * O Duplex Unicast Multicast Broadcast Why does a Layer 3 device perform 10 points the ANDing process on a destination IP address and subnet mask? to identify the network address of the destination network to identify the host address of the destination host to identify the broadcast address of the destination network to identify faulty frames 10 points Which TCP mechanism is used to identify missing segments? * sequence numbers FCS acknowledgments window size 5 points PCI and PC3 are on different networks separated by a router, RT. PC issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next? RT1 will forward the ARP request to PC3. RT1 will drop the ARP request. RT1 will send an ARP reply with its own MAC address. RT1 will send an ARP reply with the PC3 MAC address. What addresses are mapped by ARP? 5 points Destination IPv4 address to the source MAC address Destination IPv4 address to the destination hostname Destination MAC address to the source IPv4 address Destination MAC address to a destination IPv4 address 7:017 Classroom #docs.google.com 10 points Which two characteristics are associated with UDP sessions? (Choose two.) Unacknowledged data packets are retransmitted. Destination devices receive traffic with minimal delay Destination devices reassemble messages and pass them to an application. Transmitted data segments are tracked. Received data is unacknowledged. 5 points What is the prefix length notation for the subnet mask 255.255.255.224?* /26 /27 /28 O /25 7:00 7 Classroom docs.google.com 15 points What three application layer protocols are part of the TCP/IP protocol suite?
